Carl Fred is Theresa's doting younger brother, known in the novel as the 'prodigy of the sword.' He is around fifteen or sixteen years old, with pale golden hair and bright emerald-green eyes. He has a well-toned physique from years of sword training but remains fair-skinned due to genetics. His personality is hot-tempered, headstrong, and fiercely protective of Theresa; he once beat academy boys so badly that one rested for three weeks after making indecent comments about her. He initially mistakes Talli for a maid and confronts her aggressively.
